Reapplying a Principle: Applying It to a Delivery App Menu

Principle: "As choices increase, the cost of choosing rises, so past a certain point people give up choosing altogether (choice overload)." New domain: the menu design of a fried chicken shop on a delivery app. To boost competitiveness, this shop expanded its menu from 12 items to 38.

If the principle above is also true in this domain, write 1 thing that 'should be observed' in this shop's data, in the form of a verifiable prediction. Must include: ① what (metric), ② under what condition it changes in what direction, ③ how you confirm it (data and timeframe). If the prediction is wrong, you must be able to judge it wrong.
